XSIM Loves OSVVM
I am often asked does OSVVM work in XSIM? With the upcoming OSVVM 2025.02 release – YES!!! As I was wrapping up on OSVVM 2025.02 release, inspired by another instance of this question, I decided to take a look at XSIM 2024.2. »

AMD XSIM 2023.02: On the Road to OSVVM
Quite some time ago I tried out AMD/Xilinx XSIM in OSVVM. Unfortunately at the time, it was like the Talking Heads song – “We’re on a road to no where” Things have changed. We have heard good things about Vivado Synthesis starting to support VHDL-2019 features – like interfaces. Hear that Siemen’s? Are you going to let AMD Vivado pass you as well as Aldec? So my... »
Happy New Year 2024 from SynthWorks and OSVVM
2023 brought lots of changes. I started traveling again (a little bit). This was my first travels since the start of COVID. I presented papers on OSVVM at SEFUW (ESA’s Space FPGA Users Workshop), MAPLD (NASA’s Military and Aerospace Programmable Logic Devices), FPGA Conference Europe (in Munich), and at Verification Futures (both in Reading UK and Austin TX). OSVVM had 5 updates during... »

OSVVM 2022.11 Release
As I was writing the blog about the 2022.10 Multiple Verification Component example, my focus was drawn to the issue, “How do I call transactions that iterate across an array of verification components?” Solving this issue became the main goal of the 2022.11 release. The 2022.11 release includes: Updated Multiple Verification Component Test Example Created AddressBus and Stream transac... »
